Comment:
We're with USSJoin on this. Resist the hard disk manufacturers'
conspiracy.
Replying to [comment:4 zooko]:
> We generally prefer base-10 arithmetic, because it is easier for users
to use. For example, if you ask my mom how many 20-byte things she can
store in a 2-terabyte bucket, she'll probably ask "What's a terabyte?",
and if you tell her it is a trillion bytes, she'll say "Then I can store
100 billion of them."
This is not a convincing argument, since you're more likely to need to
know how many 1 MiB files, say, can be stored in a terabyte. (BTW, your
mom's estimate would be wildly wrong for 20-byte files due to overhead.)
What mattered was that there was a consistent convention. Since most uses
of "GB" (for example) still mean 2^30 bytes, Tahoe is going in the wrong
direction to reduce confusion.
